Never had an issue with overheating. I turn it on and off before and after each cut usually, but I leave it on continuously too and it never gets hot. I would know if it were because I put my hand on the motor usually when I pull it back to pin it out of the way. One thing I learned is never start the motor when it is already in contact with the log, I broke two of three teeth on the debarker bit once because it was on a hard knot when I started it, $15 bucks for a new bit. Now I always start the motor then engage the debarker into the log and haven't had an issue since. If there are lots of knots or if the log is very irregular, I'll only pressure wash it as good as I can rather than risk breaking something on a knotty or bad log, this seems to be rare with the EWP I've been milling though.
